FAQ

Q1: How do I confirm this head rotor fits my DPA injection pump?
A1: Please verify your pump’s model number and existing rotor marking. This part is specifically for the DPA series with a 6/10R specification and rotor numbers 91Y or 92Y. Cross-reference your original part number (e.g., 7139-92Y) to confirm compatibility before purchase.

Q2: What is the installation procedure for this rotor head?
A2: Installation should be performed by a qualified diesel technician. It involves disassembling the injection pump head, removing the old rotor, and carefully installing the new unit. Proper torque specifications and cleanliness are critical to prevent contamination and ensure correct pump timing.

Q3: How can I maximize the service life of this replacement part?
A3: Ensure your fuel system is clean and free of debris by using high-quality fuel filters. Regularly check for water contamination in the fuel. Using clean, high-grade diesel fuel and adhering to the engine manufacturer’s maintenance schedule will significantly extend the life of the rotor head and pump.
